In this theory Darwin proposes that 'natural selection' is the mechanism by which evolution functions. Natural selection is a change in the allele frequencies of a species which allows that species to better survive in it's environment.
The basic definition of evolution is a change in the gene pool of a population of organisms over time. All of evolution is based on genetic change.hese facts, that 1) DNA determines the nature of an organism and that 2) there are mechanisms through which DNA can be modified, are the basis of evolution. It is through these facts that evolution happens.
